It only just occurred to me that the store I work in sells this
According to the data sheet it is a blend of Acrylic polymers and selected fillers, it can take sanding and finishes and it has a shelf life of a year. Its also white and only costs £2 a tube (a lot cheaper than Acrylic resin + pigment). Being ready to apply there is no messy mixing. I already have a gun for applying it
The pre-cut tip of the dispensing nozzle has a 3 mm aperture, just about right.
I may also try knife application and mixing in acrylic paint to colour it. Of course all this may not work but that’s what experimentation is all about. Finding out for yourself.
So I’m off to make some patterns to experiment on.
Be seeing you.
